Graphene on silicon as optically tuned terahertz modulator

We show that the spectrally wideband optical tunability of terahertz transmission through silicon can be strongly improved by deposition of graphene. We measured enhanced modulation up to ΔM=24% at a low modulation beam power of 40 mW and a maximal modulation depth of up to M=99%.
